Abstract

The robot equipment for mowing grass round guardrails consists of a self-propelled carriage (7).It has pairs of castors (8) and a drive wheel (9) running in the rail's curved recess, supporting a crown wheel and pinion (13,16), with cable transmission (1) driving the mower head unit (4) with two selfdirecting wheels (5). A system of gears (17,18) changes the drive wheel direction, manually by lever (21), or automatically through the safety arms (6), mounted on swivelling spindles (15), meeting obstructions or extreme ground contours. The castors (8) cut-off power through a limiting device (22) on the lever when they reach the end of the rail. USE/ADVANTAGES - Improved safety for maintenance crews and motorists by elimination of human manning requirement.

Description

La présente invention concerne un dispositif pour faucher l'herbe sous les glissières de sécurité de route ou d'autoroute. The present invention relates to a device for mowing grass under road or motorway safety barriers.

Le fauchage sous glissière est difficile en totalité avec le matériel utilisé par les services d1entretien des routes, et représente certains dangers routiers pour les hommes qui y sont affectés ou pour les sautomobilistes
te dispositf selon l'invention est un robot automatique qui utilise les glissières comme rail de déplacement pour éffectuer la coupe des végétaux.Il est constitué d'un chassis automoteur sur roue utilisant le galbe central de la glissière pour se mouvoir dans un sens ou dans l'autre à l'aide d'un réducteur inverseur, manuel ou automatique par des sécurités de contact de sol et de courbe trop prononcée des arAetes duprofil.- Ce chassis supporte une débroussail- leuse portable modifiée et adaptée à transmission par cable. Par un dispositif de double couple conique l'ensemble à à une rotation continue possible. Un inverseur de sens de fauchage équipe l'ensemble pour un balayage complet de la tête de fauchage ou dans le cas dé rencontre d'un obstacle.
Mowing under slides is difficult in its entirety with the equipment used by the road maintenance services, and represents certain road hazards for the men who are assigned to it or for the jumpers.
The device according to the invention is an automatic robot which uses the slides as a displacement rail to cut the plants. It consists of a self-propelled chassis on a wheel using the central curve of the slide to move in one direction or in the other using a reversing reducer, manual or automatic, with ground contact safety features and excessively pronounced curve of the profile arAetes. This chassis supports a modified portable brush cutter suitable for cable transmission. By means of a double-conical device the assembly at a possible continuous rotation. A mowing direction reverser equips the assembly for a complete sweep of the mowing head or in the event of an obstacle being encountered.

La figure 1 représente, le dispositif dans son ensemble. Figure 1 shows, the device as a whole.

La figure 2 représente, en coupe, l'entraînement du dispositif de fauchage et son inverseur automatique. Figure 2 shows, in section, the drive of the mowing device and its automatic inverter.

La figure 3 représente, en coupe, la partie du dispositif automoteur et l'inverseur de sens de déplacement ainsi que ses automatis mes
te dispositfreprésenté sur la figurel est constitué d'un chassis (7) propulsé par une roue motrice (9) utilisanttle-g-a e central des glissières de sécurité comme chemin de roulement et son profil recourbé supérieur et inférieur pour s'y agripper, par destandems de galets (8). Cet ensemble supporte un moteur- thermique (12) rotatif en continue, par un inverseur réducteur composé par un couple conique double. Ce couple est équipé d'une couronne fixe (13) sur ltarbre central qui actionne la boite à vitesse de sens de roulement et d'une couronne libre (16).Un pignon conique (20) subit un déplacement å l'une ou l'autre des couronnes dans le cas rencontre d'obstacle par les sécurités de contact (3), ou dtun poteau support de glissière. Les deux couronnes (13) et (16) sont entrainées par le moteur via une poulie (14). Un ensemble de joint tournant et oxillant (2) permet par le bras de transmission par cable (1) à la tête de fauchage (4) de suivre le mouvement du sol
sur les roulettes multidirectionnelles (5). tes contacts d'obstacle (6)
ou de sol,- inversent le sens de rotation du pignon (17) par un
changement de pignon (18) de l'ensemble support (10), solidaire
du levier (21) et des arbres (15), suppork des sécurités (6).Le levier (11) par un mouvement des sécurités de contact (3) et (19),
déplace le pignon conique (20), sur l'une ou l'autre des couronnes
(13) et (16) pour inverser le sens de fauchage de la tête (4). Les
tandems de galets (8) tolèrent une déformation ou un cintrage limité, dans le cas d'un arret de glissière ou d'un endommagement de
son profil trop prononcé, ils stoppent la rotation de la roue (9).

shown on the figurel is made up of a chassis (7) propelled by a driving wheel (9) using central guard rails as a raceway and its upper and lower curved profile to hold on to, by destandems rollers (8). This assembly supports a continuous thermal motor (12), by a reduction inverter composed by a double bevel torque. This couple is fitted with a fixed crown (13) on the central shaft which activates the gearbox in the direction of travel and a free crown (16). A bevel gear (20) undergoes a movement in either 'other of the crowns in the event of an obstacle by the contact safety devices (3), or dtun support rail. The two rings (13) and (16) are driven by the motor via a pulley (14). A set of rotating and oxidizing joints (2) allows the cable transmission arm (1) to the mowing head (4) to follow the movement of the ground
on the multidirectional rollers (5). your obstacle contacts (6)
or ground, - reverse the direction of rotation of the pinion (17) by a
change of pinion (18) of the support assembly (10), integral
lever (21) and shafts (15), suppork the safety devices (6). The lever (11) by a movement of the contact safety devices (3) and (19),
moves the bevel gear (20), on either of the crowns
(13) and (16) to reverse the mowing direction of the head (4). The
roller tandems (8) tolerate limited deformation or bending in the event of a slide stop or damage to the
its profile too pronounced, they stop the rotation of the wheel (9).

L'inverseur (B) déplace un pignon fixe sur l'une ou l'autre des
couronnes du couple conique (D) double pour inverser le sens de
fauchage.
The reverser (B) moves a fixed gear on one or the other of the
crowns of the double bevel gear (D) to reverse the direction of
mowing.

Seul la position de la roue (9) au niveau.bu':'galbe central de la glissière et des tandems de galets (F), sur les arêtes des
profils de celles-ci, ont des impératifs dimensionnels et limitatifs
relatifs aux dimensions standardes des glissières.
